Other claims from this paper (8)
- Intervention effect Organic matter reduced ammonia volatilization.
- Intervention effect Subsurface placement reduced nitrogen loss more than surface placement.
- Intervention effect Organic matter increased grain yield under surface and subsurface conditions.
- Observation Equal inorganic and organic nitrogen rates produced maximum yield.
- Intervention effect Organic matter increased nitrogen content in rice grain relative to urea alone.
- Association Increasing the organic matter to urea ratio increased grain nitrogen content.
- Intervention effect Deep placement of urea and organic matter increased grain and straw phosphorus content relative to surface application.
- Intervention effect Deep placement of urea and organic matter increased grain and straw potassium content relative to surface application.
